Owner’s Manual
As a battery ages the specific gravity of the electrolyte will decrease at full charge. This is not a reason to replace the bat-
tery providing all cells are within fifty points of each other.
Since the hydrometer test is in response to a vehicle exhibiting a performance problem, the vehicle should be recharged
and the test repeated. If the results indicate a weak cell, the battery or batteries should be removed and replaced with a
good battery of the same brand, type and approximate age.
HARDWARE
Periodically, the vehicle should be inspected for loose fasteners. Use care when tightening fasteners, refer to the Techni-
cian’s Repair and Service Manual for specific torque values.
Generally, three classes of standard hardware and two classes of metric hardware are used in the vehicle. Grade 5 hard-
ware can be identified by the three marks on the hex head and grade 8 hardware is identified by six marks on the head.
metric hardware is marked on the head with 8.8 or 10.9. Unmarked hardware is Grade 2.

Unless otherwise noted in text, tighten all hardware in accordance with this chart.
This chart specifies 'lubricated' torque figures. Fasteners that are plated or lubricated when
installed are considered 'wet' and require approximately 80% of the torque required for 'dry' fasteners.
